RUDOLPH FAAS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE STANDARD CAR l AXLE LUBRICATOR COMPANY, OF SAME PLACE.

cAR-AxLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No.375,700, dated December 2'7. 1887.

Application filed August li, 1887.

To all whom it may concern:

Be it known that I, RUDOLPH Faas, a citizen ofthe United States of America, residing lin the city of Chicago, county of Cook, and

State of Illinois, have invented a new and useful Device and Improvement in Car-Axle Lu brlcators, of which the following is a specification.

This specification is tiled as an improvement to on my former invention for which Letters ISastnt No. 352,612 were issued November 16, The objects of my invention are, first, econonly in the use of the oil; second, to provide a continuously-lubricated axle-journal; third, to confine and protect the oil from accumulations or deposits of sand, dust, or other foreign substances, and, fourth, to provide a more substantially-constructed roller-lubricator .to withstand the constant wear and friction from contact with the axlejournal. I attain these objects by the mechanism illustrated in the ac` companying drawings, in which- Figure l is a vertical cross-section of a caraxle box, showing my device therein and its relation to the journal. Fig. 2 is a sectional view on line 2, Fig. l. Fig. 3 is a perspective View of the frame, showing the spring in its position.

Similarleti'ers referto similar parts throughout the drawings.

Two metal bars, D D2, of a suitable length to be placed in a car-axle box, joined by two bolts, a b, and the thin metal bar d, constitutes the frame of my device, and on which rests the roller E. The thin metal bar d incloses the end of the frame D D2 nearest and inclined with its lowerfside in such proximity to the roller E to permit the roller E to rub against 4o it to remove any excess of oil from the roller while serving the journal. The roller E is journaled in the metal frame D D2 at c, and revolving in the lubricant confined underneath it by the frame engaging with the journal A keeps it continuously lubricated. The bolt a is beveled on the side nearest the roller and serves as a scraper on that side of the roller.

In order to relieve the roller E from sudden Serial No. 246,745. (No model.)

den movement of the car axle A, or when passing over uneven rails or joints, I place underncathmy frame the steel spring F, which is formed of one piece of steel wire bent `in the form of a bow, having the two ends coiled and aixed to the bolt b, the bow resting upon the bottom of the car-axle box B, Fig. 3,'and underneath the roller end ot' my frame. This spring so placed keeps the roller in its proper position with reference to the car-axle journal 6o and relieves the roller from any violent action of the journal.

In the construction of the frame of this device I castor forge the bar D', the bolts a b, and the bar d as one piece. The other bar, D'-, is 65 then secured as shown in the illustration. I am enabled by this method of construction to place the device in the car-axle box without removing the box from the journal by -irst taking the side bar, D', having the bolts a 7o Z1 and bar d attached, and pushing it under the journal A. The roller E is next placed in its bearings, the cover K is putin place, and, lastly, the side bar, D2, is placed therein and secured to the bolts and bar by a pin, key, or other fastener that maybest suit my purpose. The bar d has its lower side placed in such proximity to the roller as to remove or scrape from it any excess of oil. The bolt a is beveled on the side nearest the roller, and with 8o the cover K scrapes the roller on that side andprevents the roller splashing the oil when revolving rapidly while serving the journal,

thereby preventing unnecessary waste. The apron 7L, which projects from the bar D2, is in- 8 5 tended to serve as a cover for that portion of the oil in the journal-box B not inclosed or otherwise protected by the frame and cover K, to prevent the oil splashing and io exclude dust, sand, or other foreign matter.

The roller-axle X with the flanges Z Z forms a spool on which is wound canvas, cloth, felt, or other porous material unt-il a proper diameter is obtained, composing the roller of my device. The cover K is of metal and made to tit in said frame D D, and is secured to one ofthe bolts a or b and fits snugly to the roller. Having thus described my invention, and being aware that lubricators have heretofore been made by having rollers engage with the Ioo journals, I do not claim such a combination, broadly; but

What I do claim as my invention, and de- Sire to secure by Letters Patent, is-

1. The combination of the roller E, journaled in the metal frame DDzat c, operatingin the lubricant Within the frameunderneatb, the beveled bolt a, bolt b, flat head bar d, and cover K, the roller end of the frame elevated by the bowed wire spring F, so that the roller E may engage yieldingly with the car-axle journal A, thus servingit continuously with the lubricant, as above set forth.

2. The steel wire spring in one piece bent in the form of a bow, with its two endsrfooiled and afxe'd to the bolt b, the bowed end rest ing underneath the roller and upon the bottom of the car-axle box, for the purpose of elevating the roller and to allow it to engage yieldingly with the carAaXle journal, as above described, for the purpose specified.

3. The combination of the roller E, frame DD?, bolts a b, cover K, and apron h, by which the oil in the car-axle box is retained nelosed and protected from sand, dust, or other foreign matter, as above described, for the purpose specified.

4. The combination of the flat head bar l, placed at an angle so as to slightly touch the roller, the bolt a, beveled ontheside contiguous to the roller, and the cover K, tted snugly to the roller, so that the roller may be clean ed on both sides while revolving rapidly in the lubricant, to prevent splashing or waste while serving the caraxle journal, as above described.
